Property Editor Help ? TEnumProperty

Can anyone tell me please, how can I make a component property read from a list of values? I don't mean to set an enumerated type and define this property from this type. I need my property to read its value from a combobox as the case in TableName property in a TADOTable, when I assign a connection to this ADOTable component I find the combobox next to TableName filled with the existing table names.
